Incomplete mesentero-axial volvulus of the stomach
Anaemia with large hiatus hernia. To delineate anatomy.

0 images remaining
- Preliminary images demonstrate a hiatus hernia with the appearance of two gastric air bubbles, one above and one below the diaphragm
- The upper and mid oesophagus are unremarkable
- Minor hold up of contrast and tertiary peristalsis in the distal oesophagus
- Mesentero-axial rotation of the stomach with the antrum and pylorus located superiorly within the chest through a large diagphragmatic hiatus, and the cardia and fundus located inferiorly
- The gastro-oesophageal junction appears normal in diameter
- The stomach is not significantly dilated
- Contrast solution passes through to the duodenum
Findings are consistent with hiatus hernia and incomplete gastric mesoentero-axial rotation or volvulus (<180°).
Mesentero-axial rotation or volvulus is less common in the adult population than organo-axial, and is most commonly incomplete (<180°). The complete form of meso-axial volvulus (>180°) is associated with severe obstruction and strangulation.
Barium study findings in this case were consistent with those at endoscopy.
